Hub 3 Intermittent Dropouts - Flashing Green Power Light

Hey, I had a Hub 3 installed by a technician just about a month ago now. Things have been mostly okay and speeds are great when it's working. However, every so often it will just completely die on me. The power light will alternate between flashing green and solid green, and I'll have no option to connect to the wifi on any device in the flat. 

I've posted the network info below, I'd be grateful if anyone was able to suggest a solution to this, or let me know if there's likely a fault and I'll need a technician out? Thanks in advance for any responses.

Re: Hub 3 Intermittent Dropouts - Flashing Green Power Light

Post the BQM link to..."Share live graph"

Also worth a quick check that all of your coax cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Disconnect all the connections and reconnect to be sure. Ensure there are no “unterminated cable loose ends or loose wires on the connectors . Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling (no clips piercing, or broken sheathing) and the wall box.

All internal cables seem fine as far as I can tell. I don't have immediate access to the outside cabling but will check that as soon as I can. Thanks for your help so far.
